Hey guys. Tomorrow i am replacing my pcv valve, hose, and rubber grommet on the passenger side of my 5.9 magnum.

Since i am replacing all three and dont plan or want to pull off the cover, im thinking of taking a sharp utility knife and cutting into the grommet and removing both the PCV valve and grommet and valve first rather than risk using pliers and pilling the valve out and risk the bottom piece breaking and falling in. Does that seem like a good waybto go about it or should i just pull the cover off? (To be honest i am trying to avoid pulling the cover off but if i have to i will)

A small, stupid, silly question upon a simple repair. But it seems wise to just ask at the moment.

Thanks guys!

 

See how tight the valve is hanging on, take it from there. I was able to place the valve, grommets, and such, without pulling the valve covers.

The valve cover gaskets were designed to be reusable, so why not play it safe and pull the valve covers? Better safe than sorry, IMHO.

 

The grommets get hard over the years, so the likelihood of them having enough flex to allow the valve to pop out is slim... but as stated above, give it a shot.

I've had part of the bottom lip of the grommet break off one time, but was able to retrieve it with needle-nose pliers... I pieced it together to make sure I had it all.

I have also made a horizontal cut half way around under the top lip of the grommet, then pushed down and tilted the valve that direction, then lifted it up... this means the grommet has to deflect less, and gives it somewhere to go... if the piece breaks off, it is on the outside.

 

Remember the old "T" bolts for valve covers... for quick removal to adjust tappets, not just show.

 

Thanks for the info guys!

I actually just finished replacing the hose, grommet, and valve without taking the covers off. Ended up cutting the grommet with two incisions and making a gap to pull the valve out and to squeez the grommet inward and pull that out.

Thanks for the info and help! Tommor is installing the rock solid ram steering kit.
